Bitcoin Implied Volatility Sits Lower Than On 92% Of Days Since 2021

Bitcoin options are priced calm by their own history. Deribit's DVOL index, which tracks 30-day bitcoin implied volatility, closed October 19 at 37.33. Only 157 of 2,037 daily readings since March 2021 were lower, so about 92% of days priced in more movement.

A CryptoQuant Quicktake by The Daily Digits flagged the reading, and we rebuilt the numbers from Deribit's own data before using them.

What bitcoin implied volatility is telling us

DVOL is Deribit's version of a fear gauge for bitcoin. It converts the prices of options expiring over the next month into an annualized expected move. A low reading means sellers of options feel comfortable and buyers are not paying up for protection.

Context helps here. The same chart shows readings above 50 in early June, so the gauge has moved a long way down since then. Bitcoin implied volatility has been parked in a narrow lane for weeks. Every daily close since September 25 sits between 34.62 and 39.12. The record low close in the series is 32.38, set on August 12, 2023, so today's level is not the floor. It is just near it, and the October 8 session briefly reached 39.41 before settling back.

Bitcoin implied volatility against what bitcoin did

The Quicktake sets implied volatility next to realized moves, and the comparison matters. The author puts 30-day realized volatility at 28.84, which means options priced about nine points more movement than bitcoin delivered. Our own calculation from Binance daily closes gives a different figure, near 32, because realized volatility changes with the method and window used. Either way, the options market was charging more than the coin was moving, and bitcoin implied volatility stayed above the realized figure on both counts.

Bitcoin itself was quiet. It closed October 19 near $81,700, and Deribit's header showed about $81,600 on the morning of October 20. The author adds that perpetual funding across exchanges printed 0.0072% on October 19, which sits inside the past month's range.

What a quiet gauge does and does not say

The Quicktake is careful about the limits. Low implied volatility does not make options cheap. Across 1,606 days from April 2022 to September 2026, the author says, DVOL priced more volatility than the next 30 days delivered on 73.7% of them. A calm market usually stays priced above what it delivers.

The author names two triggers worth watching. A DVOL close above 45 would mean traders are bracing for a move. So would funding holding above 0.01% for a week before the November 27 expiry. A close below 33 with flat funding would mean the market is getting even sleepier.

The author also points to a lean in skew. The 25-delta risk reversal for the November expiry sits at negative 3.19, so downside protection costs a little more than upside calls. The largest open interest on that expiry sits at the $90,000 and $75,000 strikes.

None of these readings predicts direction. They describe how much movement traders are paying for today.
